The lens of a kind of mode of the present invention possesses: plate substrate; Lens, its surface from described plate substrate is given prominence to and is formed; And groove, its periphery along the region that is provided with described lens of described plate substrate and forming, and from the surface of described plate substrate to the projected direction reverse direction depression with described lens.
In the situation that use the lens of the manner for example to manufacture display device, in its manufacture process, in the lensed side of arranging of this lens, for example, be coated with the resin that is applied to adhering glass substrate.Its result forms adhesive linkage between lens and glass substrate.
Now, if lens in the past, resin spreads all over less than the base material of lens and the boundary member of lens, and produces bubble.Therefore, in the past, due to the existence of this bubble, the refractive index that exists in advance determined lens when design can change, the problem of obtaining deterioration of efficiency of the light of lens.
But if the lens of the manner, the surface that is coated on the lens that the resin of lens surface is highlighted guides, and via the boundary member of plate substrate and lens, is directed to successively the inside of the groove forming along the periphery in lensed region is set.
Therefore, can prevent if easily produce the generation of the bubble of the plate substrate of bubble and the boundary portion office of lens in the past.Its result, in advance when design determined lens refractive index can be because bubble changes, lens can be brought into play the efficiency of obtaining of the light that is originally expected to.
In addition, groove is to the projected direction reverse direction depression with lens.Therefore, for example, in the manufacture process of display device, when carrying out lens and thering is the aligned in position of substrate of light-emitting component, can be from the side that has lens this groove of optical identification clearly.
Thereby the alignment mark of the lens side when making this groove as this aligned in position works, and can realize high-precision aligned in position.
In addition,, in the lens of a kind of mode of the present invention, the section perpendicular to longitudinally of described groove is that drift angle is the isosceles triangle shape of 90 degree.
According to the manner, because the section shape of groove is above-mentioned isosceles triangle shape, a dip plane reflection from outside incident light in isosceles triangle shape, the light of this reflection reflects in another dip plane.Its result, can make this incident light return to its incident its original orientation.
That is,, in the lens of the manner, can make the light that is incident in groove to its incident its original orientation total reflection.Therefore, can penetrate very bright light in the direction of the camera that groove is taken etc.Its result, in the situation that this groove is worked as the alignment mark of the lens side of the aligned in position for miscellaneous part, can easily carry out the optical identification of this alignment mark, can make the precision of the aligned in position of lens and miscellaneous part improve.
In addition, in the lens of a kind of mode of the present invention, described channel shaped is formed in described plate substrate, makes the surface of described lens continuous with the wall that forms described groove.
In the lens of the manner, the surface of lens is continuous with the wall that forms groove.That is to say, the lens of the manner has the shape that the obstruction of resin flows has significantly been reduced of the boundary portion office that makes plate substrate and lens.
Therefore, resin is directed along the surface of lens, utilizes the surperficial inclination of lens and falls into swimmingly the inside of groove.Thus, can further improve the generation preventing effectiveness of bubble of the boundary portion office of plate substrate and lens.
In addition, in the lens of a kind of mode of the present invention, described channel shaped is formed in following position, and this position is the end edge portion and the position of the distance of end in region that is provided with described lens below preset distance of face side of described plate substrate that forms the wall of described groove.
Channel shaped in the manner is formed in apart from arranging in the end preset range in lensed region.That is to say, so even in the situation that for example there is discontinuous portion because the surface of lens and the wall of groove are discontinuous, as long as channel shaped is formed in apart from arranging in the end preset range in lensed region, resin is also can be along the surface of lens directed and utilize the trend of advancing to fall into the inside of groove downwards.Its result, can prevent from producing bubble at the boundary member of plate substrate and lens.
In addition,, in the lens of a kind of mode of the present invention, described plate substrate is formed by the material identical with described lens.
According to the manner, plate substrate is formed by the material identical with lens.Thus, plate substrate has light transmission.Therefore, its major part of incident light of using when the aligned in position with miscellaneous part is reflected by the wall that forms groove, its major part of the part transmission in plate substrate beyond groove.
Therefore, in plate substrate, the amount of incident optical transmission is different from other parts at groove, can clearly identify groove and other parts.Its result, becomes easily as the optical identification of the groove of the alignment mark of lens side, can make the precision of the aligned in position of lens and miscellaneous part improve.

According to the display device of the manner, lens has the groove that forms along the periphery that lensed region is set on plate substrate surface and cave in to the projected direction reverse direction with lens.Thus, groove, by its depression, can be used as for the alignment mark of the aligned in position of the alignment mark with substrate-side and works.
In addition, in the manufacture process of the display device of the manner, for other substrates of a side bonds that have lens at lens in this side application of resin.Now, if in the past, resin spreads all over the boundary member less than base material and lens, and produces bubble.In the past, due to the existence of this bubble, the refractive index that exists in advance determined lens when design can change, the problem of obtaining deterioration of efficiency of the light of lens.
But according to the manner, resin is directed along the surface of lens, enters the groove forming along the periphery in lensed region is set.That is to say, resin is also dispersed throughout the boundary member of plate substrate and lens, can prevent the generation of bubble.
That is, the groove of the lens in the manner has that directed resin is dispersed throughout the function of guide surface of the boundary member of plate substrate and lens as the function of alignment mark with as making along the surface of lens concurrently.

According to the manner, for the bonding of lens and substrate, use resin.Therefore, for example also think that the boundary member at plate substrate and lens produces bubble.But, in the manner, resin arrange lensed region near quilt place in groove.
Therefore, when resin is placed in groove like this, resin is also dispersed throughout this boundary member, and in other words, resin close contact, in this boundary member, prevents the generation of the bubble at this part place.
Its result, can prevent that the refractive index of lens is because bubble changes, maintain expection light obtain efficiency.
In addition, for resin being guided to the boundary member of plate substrate and lens, other guide member is not set, but utilizes the groove that works and form along the periphery in lensed region is set as alignment mark.Thus, for example, in display device, can not make the thickness being stacked on substrate thicken, can this boundary member of enough resin fillings.Therefore, can suppress thickness thickening and prevent the characteristic changing of lens and obtain efficiently light.
In addition,, in the display device of a kind of mode of the present invention, described groove is by placing along the surface of described lens and directed described resin makes described resin be dispersed throughout the boundary member of described plate substrate and described lens.
According to the manner, groove is by placing along the surface of lens and directed resin makes resin be dispersed throughout the boundary member of plate substrate and lens.That is to say, resin utilization flows in the power of groove and is directed along the surface of lens, seamlessly the boundary member of filler piece base material and lens.Therefore, can prevent from producing bubble at this boundary member.Its result, can prevent that the refractive index of lens from, because bubble changes, can obtain light efficiently.
In addition,, in the display device of a kind of mode of the present invention, the refractive index of adhesive linkage is high described in the refractive index ratio of described plate substrate.
According to the manner, because the refractive index of the refractive index ratio adhesive linkage of plate substrate is high, so can suppress among the light from lens transmission in adhesive linkage, by the light quantity of the boundary surface total reflection of lens and adhesive linkage, can obtain to greatest extent the light irradiating from organic luminous layer.Its result, lens can optimally obtain the light irradiating from organic luminous layer.

In addition, although in Figure 10 and Figure 11, only the aligned in position about X-direction is illustrated, and Y direction is carried out aligned in position similarly.
Figure 12 is for the lens 100 of embodiments of the present invention and the first figure of the summary of the aligned in position of TFT substrate 210 are described.
As shown in figure 12,4 bights at lens 100, are formed with the groove 103a that is bent into right angle.
In addition,, at TFT substrate 210, in 4 positions that bight is corresponding with lens 100, dispose the alignment mark 220 of the shape that is bent into right angle.In addition, the alignment mark that is bent into right angle 220 shown in Figure 12 both can be additional to the key element forming on TFT substrate 210, also can directly be additional to TFT substrate 210.
For example, determine that lens 100 is with respect to the position of TFT substrate 210, make these 4 alignment marks 220 overlapping as shown in figure 12 with the groove 103a in 4 bights of lens 100.
Thus, as principle, complete TFT substrate 210 and the X-direction of lens 100 and the aligned in position of Y direction.And then, under this state, TFT substrate 210 is engaged with lens 100.
Thereafter, the groove 103b of the square one-tenth of either side that confirms a plurality of lens 102 have at lens 100 with the alignment mark 220 corresponding to this groove 103b X-direction whether consistent (whether overlapping according to the rules).
Figure 13 is for the lens 100 of embodiments of the present invention and the second figure of the summary of the aligned in position of TFT substrate 210 are described.
In Figure 13, the partial enlarged drawing in the bight of lens 100 and TFT substrate 210 is shown.
The both sides of each of a plurality of lens 102 that have at lens 100 as shown in figure 13, are formed with groove 103b.In addition,, at TFT substrate 210, a plurality ofly comprise that the organic EL portion 200 of organic luminous layer 204 is configured to rectangular.
In addition, a plurality of organic luminous layers 204 that belong to the same row of Y direction are the layers that send same coloured light.For example, in Figure 13, from left beginning, according to the order of the row of the layer of the row of the layer of the row of the layer of emitting red light, green emitting and blue-light-emitting, arrange, this figure repeats until right-hand member.
In addition, below, 1 row of the Y direction of organic luminous layer 204 are called to " pixel column ".
At this, if classify Yi Ge unit as with the pixel of emitting red light, blue-light-emitting and green emitting, for example as shown in figure 13, by each unit, in the left and right of each pixel column, dispose alignment mark 220.
The alignment mark 220 of the side of these pixel columns, respectively as shown in figure 13, corresponding with the groove 103b that is formed at lens 100.
Therefore, for example, as described in the explanation of Figure 12, in the situation that take the groove 103a in bight of lens 100 and the alignment mark 220 in the bight of TFT substrate 210, carry out aligned in position as benchmark, by thereafter the alignment mark 220 on the left side of at least one pixel column or right side being confirmed with the consistent of groove 103b corresponding to this alignment mark 220, can finally confirm whether lens 100 aligns accurately with TFT substrate 210.
Or, first carry out groove 103b of side and the aligned in position of alignment mark 220 corresponding to this groove 103b of lens 102, by the alignment mark 220 in 4 bights of the groove 103a in 4 of lens 100 bights and TFT substrate 210 overlapping being confirmed to carry out the whether accurately final confirmation of aligned in position.
Like this, when carrying out lens 100 and having formed up the aligned in position of TFT substrate 210 of organic EL portion 200 grades, as the alignment mark of lens 100 sides, utilize groove 103a and groove 103b.
These grooves 103a and groove 103b for example, with respect to a side (pusher side of taking a picture) of carrying out for the shooting of optical identification, not outstanding as in the past, but caves in round about.
Therefore, different from the alignment mark of standing shape in the past, can suppress picture fuzzy etc. of groove 103a and groove 103b, their picture is easily identified.
Particularly, in the present embodiment, as mentioned above, plate substrate 101 for example, is formed by same material (, acryl resin) with lens 102.
That is to say, plate substrate 101 has light transmission.Therefore, the light that is incident in groove 103a and groove 103b is reflected by each the wall that forms groove 103a and groove 103b, the part transmission in plate substrate 101 beyond groove 103a and groove 103b.
Therefore, in plate substrate 101, the amount of incident optical transmission is different from other parts at groove 103a and groove 103b, can clearly identify groove 103a and groove 103b and other parts.Its result, becomes easily as the groove 103a of alignment mark of lens 100 sides and the identification of the image of groove 103b, can improve the precision of the aligned in position of lens 100 and TFT substrate 210.
In addition, the section perpendicular to longitudinally of groove 103a and groove 103b is for example that drift angle is the isosceles triangle shape of 90 degree.
Figure 14 means the figure of an example of the section shape of the groove 103b in embodiments of the present invention.
Groove 103b perpendicular to the section of longitudinally (Y direction), be parallel to the section of XZ plane, be that drift angle is the isosceles triangle shape of 90 degree as shown in figure 14.
In this case, the incident light from outside to groove 103b incident reflects in a dip plane of isosceles triangle shape, and the light of this reflection reflects in another dip plane.Its result, can make this incident light return to its incident its original orientation.
That is, groove 103b can make the light of incident to its incident direction total reflection.Therefore, can penetrate very bright light in the direction of the camera that groove 103b is taken etc.Its result, can identify groove 103b clearly, and lens 100 and the precision of the aligned in position of TFT substrate 210 are improved.
In addition, groove 103a is also the section shape same with groove 103b, easily realizes optical identification.
Certainly, the section shape of groove 103a and groove 103b is not limited to the shape shown in Fig. 4, and the wall that forms groove 103a and groove 103b also can consist of curved surface.In addition,, at groove 103a and groove 103b, section shape also can be different.
In addition, in the lens 100 of present embodiment, form as mentioned above the wall of groove 103b and the surface of lens 102 is continuous.
But, also can there is discontinuous portion forming between the wall of groove 103b and the surface of lens 102.
Figure 15 means in the situation that form the figure of an example of the section of the lens 100 that has discontinuous portion between the wall of groove 103b and the surface of lens 102.
As shown in figure 15, form groove 103b wall plate substrate 101 face side end edge portion and be provided with between the end in region of lens 102 and have predetermined distance (L in Figure 15), therefore, produce discontinuous portion.
Even in the situation that there is discontinuous portion like this, also can, by its distance L being set as below predetermined length (Ls in Figure 15), prevent the generation of the bubble at this discontinuous portion place.
In addition, Ls such as be the bubble that can produce at adhesive linkage 270 minimum diameter half etc.The minimum diameter of the bubble that this can produce can be tried to achieve by experiment.Or, also can calculate according to forming the viscosity of the resin of adhesive linkage 270, atmosphere gas temperature when resin is coated on to lens 100, the wetting quality of lens 100 etc.
Like this, as long as groove 103b is formed at apart from the end that is provided with the region of lens 102 and is being waited by experiment as mentioned above in the preset range try to achieve, resin is just can be along the surface of lens 102 directed and utilize the trend of advancing to fall into the inside of groove 103b downwards.Its result, can prevent from producing bubble at plate substrate 101 and the boundary member (the discontinuous portion in Figure 15) of lens 102.
